Resumo: | The compacting control of earthy materials at engineering works demands great efforts and the necessity of conducting field and laboratory tests in time and space, conditioned by the work schedule always tight. It is also known that the embankment supports the efforts of substantial bodies of water with potential energy, which if, uncontrollably released, will cause tragedies and imponderable material damages. This work presents the methodology of execution and analysis of the results of field and laboratory tests performed in two experimental embankments builted during the definition of the construction s processes of the Batalha Hydroelectric Power Plant. It was collected disturbed and undisturbed samples at twelve spot in each embankment, to perform characterization tests, triaxial compression test and consolidation test. The results of these laboratory tests where compared to the results of twenty four Pressuremeter Tests (PMT) fulfilled at the same embankment. The interpretation of the PMT tests was done according to french standards. These tests provided results of Ménard Pressuremeter Modulus (EM), pressuremeter limit pressure (pl) and creep pressure (pf), which corresponds to the end of the elastic range of the material. In addition, it was performed twenty four Standard Penetration Tests in both embankments to obtain the Nspt and compare with the results of PMT. The studies developed in this research showed that these tests point out results with less variability that the ones from the laboratories and can be realized with no difficulties along the soil profile. The results achieved demonstrated that the PMT can be a very useful tool to reach the modulus of elasticity at any depth of the landfill, mainly in rolled-fill dams already operating a long time and in places where there are restrictions to remove samples for laboratory tests. |

Sabe-se, também, que os aterros compactados de barragens suportam esforços de grandes massas de água com energia potencial que se liberadas, incontrolavelmente, causarão tragédias e danos materiais incalculáveis. Este trabalho apresenta a metodologia de execução e análise dos resultados de ensaios de campo e laboratório realizados em dois aterros experimentais construídos na fase de definição dos processos construtivos da barragem da UHE Batalha. Foram coletadas amostras deformadas e blocos de amostras indeformadas de doze pontos em cada aterro, para caracterização do solo compactado e realização de ensaios de compressão triaxial e de adensamento. Os resultados desses ensaios de laboratório foram comparados com os resultados de vinte e quatro ensaios pressiométricos (PMT) executados nos mesmos aterros. Na interpretação dos ensaios PMT foi empregada a metodologia das normas francesas. Estes ensaios forneceram resultados do módulo de elasticidade de Ménard (EM), pressão limite (pl) e pressão de fluência (pf), esta correspondente ao fim da fase pseudo-elástica do material. Complementarmente foram realizados vinte e quatro ensaios penetrométricos nos dois aterros para obtenção do NSPT e comparação com os resultados do PMT. Os estudos desenvolvidos nesta pesquisa mostraram que estes ensaios apresentaram resultados com menor variabilidade que os ensaios de laboratório e podem ser realizados sem muitas dificuldades ao longo do perfil de um aterro compactado. Os resultados alcançados mostraram que o PMT poderá se tornar uma ferramenta de grande utilidade para obtenção do módulo de elasticidade em quaisquer profundidades de aterros compactados, principalmente em barragens antigas e em locais destas onde possam existir restrições para retirada de amostras para ensaios de laboratório.Made available in DSpace on 2014-07-29T15:18:21Z (GMT).
